Ooops! I just sent the wrong version, which was missing support for points as 
well. 

Also note that the syntax is 
v.drape [ -B | -C ] in=trails output=trails3d rast=elev_meters

where the -B or -C refere to bilinear or cubic interpolation, default is 
nearest neighbor.

Attached is the current version:
